Yeah, i know. This patch series depends on two other ones:

 * https://lkml.kernel.org/netdev/20200723074946.14253-1-kurt@linutronix.de/
 * https://lkml.kernel.org/netdev/20200720124939.4359-1-kurt@linutronix.de/

One of them has been merged, the other is being discussed. That series
includes the 'ptp_header' and the corresponding functions. So, for
compile testing you'll have to apply that series as well.

Thanks,
Kurt
